PEDAL-MOUNTING.

SPECIFICATION forming part of Letters Patent No. 755,301, dated IVIarch 22, 1904.

Application filed June 24, 1901.

T0 ctZZ whmn it may concern:

Be it known that 1, Louis LEMIEUx, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Peclal-Wlountings, of which'the following is a specification.

The object of my invention is to provide a pivot-bracket for piano and organ pedals and similar levers of a simpleand cheap form of construction, which will not work loose and which while holding the pedal-lever firmly against side motion will be practically frictionless.

To such ends my invention consists, in substance, of an inverted U -shaped yoke or bracket formed of resilient spring material adapted to be secured to the casing or support in such manner that the sides thereof will be under constant tension, such side pieces or resilient yoke sides being provided with a suitable bearing or pivot device adapted to coact with suitable bearing or pivot devices or pivotal members upon the pedal or lever to form a bearing or pivotal joint therefor.

In the accompanying drawings, forming part of this specification, in which like letters of reference designate corresponding parts in the several views, Figure l designates a top plan view in perspective of a piano-pedal secured in position by my improved form of pivot-bracket. Fig. 2 is a view of the bracket shown in Fig. 1 with the pedal removed therefrom looking in the direction of the arrow in Fig. 1. Fig. 3 is a view of the upper portion of Fig. 1, the end of the pedal-lever and of the bracket-standards or yoke sides being shown in section. Fig. 4 is a side view of the end of the pedal-lever. Fig. 5 is a sectional view, similar to Fig. 3, of a pivot-bracket of a slightlymodified form of construction from Figs. 1, 2, and 8, in which modified construction the pivot-points carried by the bracket are replaced by sockets connecting with pivot studs or pins on the pedal-lever, as shown in Figs. 6 and 7. Fig. 6 shows a modification in construction of the end of the pedal-lever to go with the bracket, as shown in Fig. 5, the pivot-points being on or fixed to the lever and Serial No. 65,761. (No model.)

being formed by a pin which passes through the end of the lever. Fig. 7 is a modification of Fig. 6 and shows the pivot points or studs cast on and projecting from the lever. Fig. 8 is a plan view of one of the ears or projecting ends or base-plates of my pivot-bracket with a modification in shape of the screw or bolt hole by which it is fastened to the rest or support. This modification shows an oblong hole or slot, so that the sides of the yoke may be spread and the pedal putin place and pivotally connected to the bracket after the bracket is fixed to the rest or support. Fig. 9 shows two sectional views of the pin referred to in Fig. 6, which is made with a flat place in the center and is inserted in the mold when the pedal is cast, and thus cannot turn or be moved, but is rigidly fixed in place in the end of the pedal-lever. Fig. 10 is a separate view in section of the end of the pedallever, as shown in Figs. 1 and 3, in order to clearly show the indentations or sockets in the end of the lever. Fig. 11 is a view of the inside of the yoke shown in Fig. 5 looking toward the inside face of the yoke side, marked 4; and Fig. 12 is a horizontal section across Fig. 5 on the line a a: looking down. These views show the upright groove in the yoke sides in which the pivot-point is engaged, whereby the pedal-lever is the more easily in serted in place.

In the form of my improved pivot-bracket for pedal-levers for pianos, &se. (shown in Figs. 1 to 3,) such bracket consists of a yoke, usually of the shape shown in either Figs. 2 or 5, consisting of a strip or strap-piece 1 and 1 of resilient spring metal, such as steel, provided with the base-plates 2 and 2', having securing-holes 3 and 3 for the reception of suitable securing screws or bolts, and from these base-plates extend upward the yoke sides 4L and 1, which are joined together at the top, so as to form an inverted-V-shaped spring portion 1 in Fig. 2 or 1 loop shape, as in Fig. 5. Such pivot-bracket is provided at the proper height in the straight standards 4 and 4: in Fig. 2 with any suitable pivotiug journal members 6 and 6, coacting with suitable journal formations 7 and 7 (see Fig. 10) upon the pedal-lever 8. These coacting journal parts may consist of pivotpoints, as shown in Figs. 1 to 3, coacting with suitable conical perforations in the sides of the pedal-lever 8, as shown in Figs. 1, 2, and 10, or of suitable indentations 9 and 9' in the sides of thebracket, as shown in Fig. 5, coacting with studs 10 and 10 in Fig. 7, or 11 and 11 in Fig. 6, to form such pivotal joint between the bracket and the pedal-lever.

In the modified construction of Figs. 5 and 6 I show the preferred form, where the sockets are in the bracket 9 and 9' and the engaging points of the pivot are in the pedal and are formed by a pin east in the end of the pedal-lever. This pin is shown in section in Fig. 9, and I flatten a place in the center, as shown, so that when in the pedal-lever it cannot either rotate or move laterally. Thus the bearing is confined to the pivot-points of the pin at each end in the sockets 9 and 9.

In Fig. 8 I show as a modification the screwhole in the base-plate made oblong or in form of a slot. In this way the bracket can be fixed to the casing or support before the pedallever is pivoted to the same, and then after the lever is inserted and fixed pivotally to the bracket the bracket can be screwed tightly to the casing after the resiliency of the sides has brought the pivot-points and sockets in close contact, so that there may be no lost motion in the pivoted joint.

In either of the constructions shown the two side pieces 4 and 4: when in their normal position and secured to the casing or support on one side or the other (above or below) of the pivot-point are closer together than on the other side of the pivot, in the construction shown in Fig. 2 such narrowest point being at the bottom, and in the construction shown in Fig. 5 at the top or just above the pivotal sockets, and in either construction it will be seen that the natural resiliency of the spring sides 4: and fk will force the bracket to maintain the positions shown and described. This is for the purpose of allowing the end of the lever to be easily entered between the sides when about to make the pivotal connection,

the space between the two pivot connections being normally narrower than the pedal-lever.

I am aware that pivot-brackets have been made; but they have not been made in form of a resilient yoke, and usually a screw is necessary to keep the sides together and the pivot-points in the sockets, and whenever the screw gets loose there is play or lost motion in the pivoted joint, and if the screw is set too hard there is friction in the pivoted joint, which makes it worse than worthless.

By my invention friction is avoided and the pivotal connection is made positivetwo things absolutely necessary. Besides the adjustment is simple and the cost reduced to the minimum.

Having thus described my invention, what I claim as new and original, and desire to secure by Letters Patent, is

1. A bracket for pivotally mounting pedallevers to, and in combination with, the frame of a musical instrument, which consists of one piece of resilient metal in form of a yoke, the two ends of which are fixed to the frame of the musical instrument, the end of the pedal being pivotally held in place between the sides of said yoke by the resiliency thereof, substantially as shown and described.

2. A bracket for pivotally mounting pedallevers for musical instruments, which consists of one piece of resilient metal in form of a yoke, the two ends of which are made flat or set substantially at right angles to the sides of said yoke, and either one or both of said ends having an oblong hole or slot through which by a screw the bracket is fixed to the musical instrument, and whereby the sides of said yoke are made adj ustable toward or from each other, substantially as shown and described.
